To provide a material for pressure measurement with which color development is obtained that exhibits superior gradation in a high pressure region.SOLUTION: Provided is a material for pressure measurement that includes a substrate and a pressure sensitive layer, the pressure sensitive layer containing a polymer matrix including a high molecular compound of 1000 or greater in molecular weight, and a microcapsule enclosing an electron donative dye precursor and a solvent and an electron acceptor compound, the pressure sensitive layer further including a color-revelation layer having an electron acceptor compound and a polymer matrix and a color-developing layer having a microcapsule. The substrate, the color-revelation layer, and the color-developing layer are included in the order stated, the thickness of the color-developing layer being half the thickness of the color-revelation layer or less, the color-revelation layer having a recess, with part of the microcapsule penetrating into the recess. The arithmetic mean roughness on the outermost surface of the color-developing layer that is on the side opposite the substrate is 1.5 μm or greater, the particle size d2 of the microcapsule is 1 μm to 50 μm, and a concentration difference (ΔD2) derived by subtracting a concentration after color development by applying pressure at 100 MPa from a concentration after color development by applying pressure at 500 MPa is 0.1 or greater.SELECTED DRAWING: None

A scratch-off coating is provided which includes a first layer of ink comprised of a water-based ink; and a second layer of ink comprised of an ultraviolet-cured ink layered over said first layer of ink, wherein upon application of a scratching force said first layer of ink and said second layer of ink are removable from a surface on which said first layer of ink and said second layer of ink are applied.

Disclosed are multi-layer exposed substrates and methods of making and / or using the substrates, the substrate including: a first layer comprising a first opacifying material; a first color material applied to a first side of the first layer comprising the first opacifying material, the first layer comprising the first opacifying material being positioned to cover the first color material; and a second layer comprising a second opacifying material applied to a side of the first color material opposite the first layer comprising the first opacifying material, the second layer comprising a second opacifying material being configured to change from an opaque state to a transparent state upon application of a first predetermined energy to expose the first color material underlying the first opacifying material, and the second opacifying material being configured to change from an opaque state to a transparent state upon application of a second predetermined energy.
